Calculate the volume, in milliliters, of a 0.211 M solution of NaOH that will completely neutralize each of the following. 2.30 mL of a 0.820 M solution of H2SO4. Express the volume in milliliters to three significant figures.

Explanation:

Hello,

In this case, as the reaction between sodium hydroxide and sulfuric is:

We can notice a 2:1 molar ratio between the base and the acid, for that reason for the titration at the equivalence point we find:

Which in terms of concentrations and volumes is:

In such a way, solving for the required volume of base we find:

Best regards.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
